Which shows the equation below written in standard form? 13 - 6x = (2x - 5)2 + 3
a. 4x2 - 14x - 15 = 0
b. 4x2 - 14x + 15 = 0
c. 4x2 - 26x + 15 = 0
d. 4x2 - 26x - 15 = 0

The correct option is (b)

Step-by-step explanation:  The given equation is

We are given to select the correct standard form of the above equation.

We will be using the following formula:

From equation (i), we have

Therefore, the correct standard form is

Thus, (b) is the correct option.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
